This is all that it does now when i plug it in, it repeats the same menu's regardless of how long i leave it unplugged, I can't tell whats in the truck for software now, it runs and drives fine, but my trinity is locked now.
You'll need to call from the PC so we can force the update on since the tool is locked.
Once the update is on, it will allow you to restore in recovery mode, then you can tune away
